Unit was not the one in the pictures. It was a similar unit but this unit was on the ground floor, so it was darker. This wasn't helped by a couple of the lights not working.
Also, something was wrong with the air conditioning, so the unit was constantly humid, regardless of the temperature we set.
The mattresses on the beds were the firmest we had ever experienced, and we like firm mattresses.
The communication with Yefeng was excellent - he was in touch constantly and was able to quickly help with a hot water issue.
The location of the unit was great, being a short walk to Asok BTS, Terminal 21, a 7/11 and multiple cafes.
